    Abstract: An ink tank (1) comprises a housing detachably mountable on a liquid jet recording apparatus, which is capable of retaining liquid directly in the interior thereof, a supply portion (13) for supplying liquid retained in the housing to the recording apparatus and a communication portion (12) with the air outside for communicating the interior of the housing with the air outside. For this ink tank, the supply portion (13) and the communication portion (12) with the air outside are integrally formed, and at the same time, a plate member is provided to make the interior of the housing a closed space by joining the plate member to the housing, and then, erroneous installation prevention portions are arranged for the plate member to prevent the installation on the position other than specifically designated for the liquid jet recording apparatus. With the structure thus arranged, the ink tank (1) makes it possible to easily enhance the dimensional precision of the coupling portion with the recording apparatus, and the erroneous installation prevention portions as well. Thus, without depending on the precision of an ink tank as a whole, it is possible to enhance the reliability of the installation on or coupling with the recording apparatus.
